Data analyses The density values of foliage dwelling spiders were calculated on the basis of the net area as a unit (0.50 m

2

). Dominance categories were applied according to Palgren's gradation (1972): > 5 % dominants, 5-2 % influents, 2-0.2 % recedents, <0.2 % occasional. For separating the guilds and analysing the guild structure I applied works by Gunnarsson (1988), Jennings et al. (1990), and Nyffeler and Benz (1987). Results Spider taxa: Spiders of 15 families, 40 genera, and at least 60 species were collected from foliage of Picea abies (Table 1). 8 species were found only in June, 12 in October, 40 species were found on both occasions. Philodromus glaucinus Simon, 1870 is new to the Hungarian fauna. Altogether two specimens of the species were found, a female in June, and a juvenile in October. Measurements of female : total length 2.8 mm, carapace length 1.5 mm, carapace width 1.1 mm. P. glaucinus belongs to the P. rufiis species group. Epigynum characteristics: median septum broad with parallel sides. Internal spermathecae organs are visible through integument (Fig. 1). Distribution in Mediterranean countries (Algeria, Tunisia, Sicily, Spain, Greece, Macedonia, Syria) (Simon 1914). The species was found in Israel in an apple orchard and a small wood of eucalyptus, under the bark of trees (Levy 1977). Spider numbers, life stages, sex ratios: The total number of collected spiders is 3545. Most of them were juveniles (89.3 %), followed by females (8.1 %) and males (2.6 %). The distributions of spider life stages significantly differed between June and October. In June 31.5 % of the animals were adults, while only 2 % in October. Spider densities: The mean densities in June and October, estimated against net surfaces differed significantly. The mean density values of the 18 biotopes showed great variability (XJune= 11.54 ± 6.46 XOct. = 55.66 ± 25.26) Fig. 1. Philodromus glaucinus Simon, female epigynum
